Coulombe pitched one-third of an inning in Wednesday's 7-3 win over the Red Sox, allowing no runs or hits but issuing a walk.
The southpaw has put together an extended stretch of solid performances since late August. Coulombe has a 3.60 ERA, .176 BAA and .269 wOBA allowed in the five innings spanning his last nine appearances, a stretch during which he's also compiled a pair of holds.
